AI Technical Summary

Technical Problem

Traditional natural gas pipeline fittings are difficult to operate in confined spaces or environments with obstructed visibility, have poor sealing performance, are prone to loosening, and cannot simultaneously meet the requirements for electrical conductivity and medium transmission, leading to an increased risk of leakage and poor conductivity.

Method used

It adopts a magnetic self-sealing design, which uses the opposite attraction force of positive and negative magnets to achieve precise docking. Combined with the tight contact of elastic gaskets and copper gaskets, and with threaded adjustment and multiple fixing structures, it ensures the stability and sealing of the connection.

Benefits of technology

It enables rapid and precise docking in confined spaces, enhances sealing and anti-loosening capabilities, adapts to installation needs in multiple scenarios, reduces the risk of leakage and poor conductivity, and simplifies the equipment structure.

Abstract

This utility model discloses a magnetic self-sealing quick connector for natural gas pipelines, relating to the field of natural gas pipeline technology. The magnetic self-sealing quick connector for natural gas pipelines includes a male connector with an array of fixed grooves on its surface. A U-shaped sleeve is fixedly connected to one side of the male connector, and an elastic washer is fixedly connected to the recess of the sleeve. Copper gaskets are movably mounted on both sides of the elastic washer. A positive magnet is fixedly connected inside the sleeve. A connecting body is movably connected to the side of the copper gasket away from the sleeve. In this magnetic self-sealing quick connector for natural gas pipelines, the combined effect of the magnetic attraction force and the pre-tightening force of the elastic washer ensures that the copper gaskets are always in tight contact, reducing poor contact caused by vibration or slight displacement. The double fixing structure of the elastic ring and the connecting nut within the annular groove further enhances the anti-loosening capability of the terminal connection.
